Relationship between greenhouse gas emission, energy consumption, and economic growth: evidence from some selected oil-producing African countries

Abstract

This paper investigates the relationship between greenhouse gas emissions, energy consumption, and output growth among African OPEC countries (Libya, Nigeria, Angola, Algeria, Equatorial Guinea, and Gabon) using the panel autoregressive distributed lag model (PARDL) estimated by means of mean group (MG) and pooled mean group (PMG) for the period 1970-2016. The paper estimated three panel models comprising the components of greenhouse gasses which includes nitrous oxide, carbon dioxide (CO2), and methane and examined their relationship with economic growth and energy consumption. The findings of the study showed evidence of a positive impact of economic growth on both CO2 and methane emissions in the long run. Its impact on nitrous oxide emissions although positive was found to be statistically insignificant. Energy consumption was also found to produce an insignificant positive impact on CO2, methane, and nitrous oxide emissions in the long run. In the short run, economic growth exerts a significant positive effect on methane emissions; however, its effect on CO2 and nitrous oxide emissions although positive was found to be statistically insignificant. Energy consumption produces an insignificant impact on all components of greenhouse gasses in the short run. In addition, our empirical results showed the presence of a non-linear relationship between methane emissions and economic growth, confirming the existence of the environmental Kuznets curve (EKC) only in the case of methane emissions model.

Do economic endeavors complement sustainability goals in the emerging economies of South and Southeast Asia?

“…Contrarily, Bilan et al (2019) and Alola et al (2019) ascertained that the widespread use of renewable energy consumption fortified the environmental quality in the respective countries. Further, by using the sample of African countries, Yusuf et al (2020) in their study exhibited that energy consumption has not influenced carbon emissions significantly during the study period. Such kind of uncertainty motivated us to examine whether nonrenewable energy consumption leads to CO2 emissions in the selected countries.…”

Revisiting Natural Resources—Globalization-Environmental Quality Nexus: Fresh Insights from South Asian Countries

“…CO 2 emissions are the most significant contributors to GHG emissions, followed by CH 4 and N 2 O. CO 2 emissions are primarily produced from the consumption of energy, transportation, and industrial output [52]. CH 4 is generated during the consumption of natural gas, oil and coal [53], while N 2 O emissions are emitted from agricultural activities [54]. The ecological footprint, on the other hand, is a modern instrument to measure the environmental quality, which reflects the ecological and biological aspects of the earth.…”
